Been trying to get onto Soulseek for three days now. Seems to be down. Anyone know why? cheers.

No idea, maybe it's temporarily down?
But hey, why don't you use the Gnutella Network?
How about LimeWire?

i find soulseek has a much more extensive search and is particularly good at finding obscure stuff (music mainly). i have tried Limewire in the past (and I use KaazaaLite) but found it rather 'mainstream' in terms of content.
